Exception handling and testing it with Minitest
Exception handling is not something we always think of in advance. Instead of being proactive, we are almost always reactive. We wait for the disaster to happen and than we adapt our code for it.

The only thing that is constant is change demanded by the environment. To read more, check out the Flexible Design article.
PR Log: Turn Pull Requests into Changelog Entries
tf/pr_log (MIT license) is a small command line tool which fetches recent pull requests from a GitHub repository and inserts changelog items. It encourages handcrafted changelogs and plays nicely with existing changelog content. It uses GitHub milestones and labels to filter items and insert custom prefixes like “Bug fix”. In most cases it can parse its configuration automatically from the project’s gemspec. [more inside]
